After the news that Apple is getting ready to release its OS X 10.7.5 to developers, the company seeded its Build 11G15 yesterday. This would allow devs to focus their efforts on the following:
- Graphics performance and quality
- Image and media importing, editing and viewing
- Networking reliability and performance
The build weighs 937 MB, although a 1.87 GB combo version is also available for users who want to upgrade their device from any version of the OS X Lion. Prior to this, Apple released the OS X 10.7.4 last May 2012. It brings various improvements, including a fix for the FileVault bug.
Fixing the FileVault Bug with OS X 10.7.4
The update that was seeded last May is recommended to all OS X Lion users because it patches a security bug found in the configuration of the previous 10.7.3. The FileVault bug was discovered earlier in May, which allows the creation of system-wide debug file that display user credentials like passwords. On a positive note, it only affects users who carried over their FileVault setting from OS X Snow Leopard and switched to its successor.
Furthermore, users who bought their Mac with a pre-installed OS X Lion are not affected by the OS X 10.7.3 issues. That’s because Apple’s FileVault 2 is not affected.
In addition, the login data can also be viewed when booting a Mac into FireWire target disk mode. The bug will open the drive as a disk or use a superuser shell to mount the main system partition. Also included in the update is a fix for the “Reopening windows when logging back in.” It is a box that is perpetually checked when a user logs out or shuts down his or her Mac.
Just like the Build 11G15, it previous update has a client combo. It features the same fixes as the OS X 10.7.4, as well as general improvements in file sharing, migration and security. Also adding to its capabilities is the Server Admin 10.7.4, which brings the latest releases of Podcast Composer, Server Admin, Server Monitor, System Image Utility, Workgroup Manager and Xgrid Admin.
Although the latest OS X Lion build has no known issues, its timetable for public release is still unknown. Apple announced that they will be launching their new operating system, Mountain Lion, some time next month. This could mean that they will roll out the OS X 10.7.5 prior to that. However, the company occasionally releases maintenance update for the operating system even if its successors are already available.
